I'm running the adaptronics plug and play for the series 6 RX-7, I just got a Mac Boost solenoid and am really having trouble installing it. I've searched and read around and still can't seem to find anything. Anyone know how to install this? or have pictures?

The solenoid has two black wires coming out of it, i dont know which wire is what or where they go. Also having trouble with which vaccum lines go where.

Lastly, is there anything i have to do in the settings on Wari to enable the boost solenoid? do any connections go directly into the adaptronics ecu?

Thanks for the help!

If you still have the factory harnness with all the stock connectors its pretty simple, read the thread link.

figured out the wiring i think, just confused on which vaccum lines go where. I have one coming from the wastegate and one next to it that seems to be coming from a manifold or the y-pipe. not sure which goes to port 1 and 2 on the mac solenoid

Hi Omar,
OK I think this is the way to do it:

Port 3 of the Mac valve goes to the compressor exit.

Port 2 of the Mac valve goes to one wastegate actuator port. The other actuator port is closed.

Port 1 of the MAC valve is open to the air.

Thanks.

I just got asked this question by one of our dealers so I will post the info in the open;


Here are a few ways to have multiple levels of boost control( one may need more than one boost level when using the dual maps);

1) Connect a switch in series with the boost control solenoid. Then when the switch is on, the boost will be ECU controlled. When it's off, the boost will be set by the wastegate actuator

2) Connect a switch to a digital input on the ECU (other side to ground) and set the digital input as "Boost 1".

Then when the switch is off, the ECU will read the duty cycle from its normal map. When the switch is on, the ECU will limit the duty cycle to the level set in the "Boost 1 DC" setting, so you can give an artificially lower boost (but still higher than the actuator setting).

4 settings of boost control look like this (using two inputs - and both at the same time gives the "3" combination), plus a switch to disable the boost control solenoid completely. I do my 4 settings using a 2 pole 4-position rotary switch so the driver doesn't have to remember the combinations or anything.

Then:
Boost 1 input shorted to ground = limited to the "boost 1" setting Boost 2 input shorted to ground = limited to the "boost 2" setting Both boost inputs shorted to ground = limited to the "boost 3" setting Both off = maximum boost (set by the boost duty cycle vs RPM)

What about a rotary switch with different resistance/voltage?

Or is this something only possible in the e1280?

Hi guys,

The Select ECU does the multi boost level with digital inputs set to discrete/defined/pre-set duty cycles so the appropriate switch to use for this kind of setup is something that just switches to ground.

Thanks.

Here's How I set up my Wastegate lines




I have a select as well..... But i'm actually using a Borg Warner EFR8374 which comes supplied with a EBC solenoid on the front of the compressor housing. Either way... they'll work.

So Make sure you watch the video Mamba posted above and don't over complicate things. If you open your select pdf manual it tells you which aux input you'll be using for your boost control.

But just to clarify really quick. To set it up in the software. Do this.

1) open Wari (if your not hooked up to your car) load it from the saved file.
2) once your looking at the tuning software click on the "AUX Out" tab.
3) Go to the Aux Output Number drop down menu and select "3 - High current (3A), PWM capable.
4) Under the drop down menue labeled "Type" select "Wastegate."
5) Frequency should be at "25 Hz."


Now that youv'e set it up in your software. You should make sure your solenoid is working. So on the same page as you were above...the "Aux Out" tab, and as long as you've already installed your solenoid. Click the "invert" button and listen to see if your solenoid "CLICKS." If it doesn't, you've Incorrectly wired the solenoid into the ecu. If you do hear the "click." Then your solenoid is now useable.

Now here is what I noticed using the EFR Electronic boost control solenoid that is supplied with the EFR8374 and other models i'm sure... On the EFR training manual it states that the "VENT" on the solenoid is directly opposite of the inlet. ANd just to clarify, if your looking directly at your EFR the inlet is pointing towards your right, and the vent is pointing opposite that to your left. The outlet is pointing towards you. .... So what i've noticed is that witht he Wastegate configuration in the above picture.. (Which I'm currently running) I couldn't get the ebc to work at all. After a couple days going through my entire system... I got pissed off and pulled the line off the outlet and put it onto the Vent.....Made a pull and What would you know... Perfect boost control. I keep pulling up the training manual to double check if i went somewhere wrong or if I incorrectly installed something but it works Like this. Maybe it has something to do with running dual wastegates? I dont know....but like I said. It works great.
